IMPROVEMENT l'Ne-P LOW-CLEVIS.

Specification forming part of Letters Patent No. 52,123, dated January23, 1866.

Be it known that I, LOYAL W. ALDE Fosterville, in .the county of Gay ofNew York, have invented a 11 Improvement in a S N, of uga and State ewand useful pring-(Jlevis for Plows igs; and I do hereby deolare thefollowingto be a full, clear, and exact description of the same,reference being had to the accompanying drawings, makinga part of thisspecification, in whicl Figure 1 represents a top view of the clevis anda portion of the point of a plow-beam to 2 represents a. side view ofthe same. Fig.3 represents a section through one of the cylinders thatcontain the springs for allowing the olevis to yield m 11. suddenshocks.

Similar letters of reference, where they occur in the separate figures,denote like parts in all of them.. y I

I am aware that a spring has been used in ease the concussion or shocksthat the plow receives and relieve the horses shoulders, and I do nottherefore claim, broadly, such application, but claim the oh -Iconstruct and apply the spring-clevis. v

My invention consists i1 made in two sections, by an equalizing-bar,

1 a spring-elevis connected at their front to which the team is msthrough which and beam a pin may pass e of draft, and pivoted in toadmitof this raisas will be explained. ers skilled in the art to make 1 willproceed to de-' rence to the drawings. The two sections A A maybe alike,or made in right and left hand pieces, if" they differ in' any essentialpart, and they may be made of cast orwrought metal, or parts of each.Upon each of the sections there iscast or formed a suitable projection,a, bolted or pivoted to t section is holding a through a plate on the toraise or lower the lin at their rear tothe bea ing or lowering, Toenable o'th he beam B. Upon each cast or wrought a cylinder, b, forspring of metal orany other suitsprings, pivoted at their by which theyare to be J arms or lugs "c, by suitable holes in which the front end ofthe entire clevis may be raised up or let down to change the line ofdraftto suit the depth at which the plow is to run or the height of theteam. This may be done by a pin or bolt, (1, passing through said lugsand through a plate, 0, secured to oriu the beam, and furnished withsuitable adj usting-holes e e, &c.

l) D" are rods extending into the cylinder 1), and surrounded therein bycoiled springs f, or held therein by rubber or any otherfsufli= cientlyelastic and durable springs. Upon the ends of the two rods D D is placedan equalizing-bar, F, having slots 9 made in it to reeeixe the bolts z,thatpass through said slots and through the projecting ends of the rods,which are properly flattened out, shouldered, or tenoned, so as to allowthe gains in the equalizing-bar to move over or past them. To thisequalizing-bar F, which can be adjusted laterally, the double-tree hookG is fastened. The bolts t i may he square-shan'ked bolts, so as topassthrough the slots and square holes through the bars or rods D, and notturn around in them, The pin 61 may be made to fit into a hole, m, inthe head of the screw-bolt n, by which the sections are pivoted orfastened to the beam for the purpose of removing said bolt n,- and inthe head of the bolt 11. isformed a'recess, r, to serve as a wrench fortakin ningon thenuts of the several bol the parts are held together.

Having thus fully described my invention, what I claim therein, and.desire to Letters Batent',..i s'-.- 1 In combination with th ts by whiche sectional platesand rear to the beam and to at their front ends,neeted thereto, substannd for the purpose demade adjustable there theequalizing-bar con tially in the manner a scribed.
